Appendix A Command Reference

XGIF

Generic InfoFrame Data

Class

InfoFrame Generator (IFG) parameter

Description

Writes generic InfoFrame packet data. This allows you to emulate any InfoFrame type

(including vendor-specific).

Note: The HDMI specification (section 5.2.3.2) requires that an HDMI packet must be

transmitted at least every two VSYNC periods, or the receiver will drop out of HDMI mode.

A Generic InfoFrame packet can be used for this purpose by enabling its repeat bit (see the

IFTR

command).
